1 Application areas There is a large variety of application areas for MobileWall. Some of them have already been identified by the legislator who provides special authorisations for e.g. elimination in areas, where illegal mobile communication, if it is not suppressed, could be a direct threat to life and limb.

§ Prisons § Conference and meeting rooms, hotel § Universities and schools § Court § Churches, cinemas, theatres, filling stations


2 Detection of mobile communication by MobileWall MobileWall Detector detects energy on the corresponding uplink frequency bands with listening to transmission power of mobile devices. Therefor the whole uplink frequency band must be monitored at any time. MobileWall Detector is a passive device that, by using a special antenna, listens to transmission power of illegal mobile devices, doing so around the clock all over the mobile networks on up to 12 bands simultaneously. As soon as unwanted mobile activity is detected, an alarm is triggered and the monitoring PCs are notified about frequency range and strength of the detected signal. In most cases, the illegal signal will be detected by several adjacent devices simultaneously with differing transmitting power strengths. By using this information the monitoring system ControlCenter can ideally quite accurately pinpoint the position of the detected illegal mobile device and, therefore, the staff for its confiscation. 2.1 Specific characteristics of MobileWall detection MobileWall is an advanced system developed based on extensive experiences with previous versions. 2.1.1 Detector module and longevity MobileWall is a modular system. Each MobileWall device has a slot for the detector module that enables the detection function of MobileWall. By means of this architecture the devices can be equipped with different detector modules according to the country or place of destination. Since – especially with the upcoming LTE frequencies – the required frequency ranges differ widely from country to country, the flexible equipment of MobileWall is an essential feature. MobileWall’s modularity has great advantages: 1. If required, more bands can be ordered, e.g. Wireless LAN or satellite telephones. 2. When changes in the frequency spectrum occur (as for example today LTE, hereafter 5G), future-oriented MobileWall can easily be upgraded by replacing the detector module. 2.1.2 Detection coverage radius/sensitivity MobileWall Detector monitors only a small radius, thereby minimising the risk of false alarms and greatly improving the pinpointing of illegal mobile phones. Moreover, there is no possibility to avoid a detection by establishing a shielding around the device, as is the case with wide range detection solutions for entire buildings. 2.1.3 Speed of detection As already described, sending a short email or an SMS is a matter of a split second. If the detection system simply aims to find out about (detect) an illegal mobile phone, the speed of the detection process is obviously of secondary importance. But if the system aims to ensure that at no time sensitive data are sent/exchanged or uncontrolled communication with the outside world takes place, detection speed has to be incredibly high. This is the only way to ensure that the signal of a very short transmission pulse (e.g. SMS) can be detected, an optional eliminator module be activated, and the data transmission can be disrupted still on time so that the exchange of data completely fails. MobileWall is able to activate the optionally integrated eliminator within 200 milliseconds and to disrupt any mobile activity in this tiny fraction of a second.


3 MobileWall system components MobileWall consists of several components that are essential for the proper functioning of the system. 3.1 PriSec ControlCenter (PS-PC-CC) Fig.: PriSec ControlCenter Appliance The PriSec ControlCenter is the central management system for the entire range of Gerdes AG’s PrisonSecurity products: PrisonPhone, PrisonMedia, MobileWall etc. The PriSec ControlCenter 19’’ server PC is delivered as a finished appliance with the operating system and the PriSec ControlCenter software already installed. PriSec ControlCenter handles the management of all connected MobileWall devices and provides a web front-end for monitoring of the devices installed and the administration of the inmates’ accounts. Further Characteristics:

§ Power supply: Standard IEC connection 230 V / 50 Hz § Hard disk: 2 x 1 TB, RAID § 2 RJ-45 1Gb / s connectors § Operating system: Linux § Adjustment of the sensitivity of the receiver § Control of the the frequency bands to be monitored § Sensitivity adjustment of the alarm limits for the radiation reference values § Setting the operating modes of the devices § Graphical representation / map of all devices in the network with display of detected

signals and alarm activation in case of: § Loss of connection of the MobileWall detectors § Loss of connection to the central control unit § Short circuit / overload on bus connection § Violent opening of the devices § device temperature out of the allowd range

3.1.1 Workstations (PCs) Almost any number of PCs can be connected via network that provide the Web browser-based access to the PriSec ControlCenter, where all necessary settings can be made.


3.1.2 Configuration of the MobileWall devices with the ControlCenter After the MobileWall installation phase in which the parameters and positions of the single MobileWall devices are set in the PriSec ControlCenter software, the system works completely independently, i.e. without further user input. The available setting options include:

§ Adjustment of the detector sensitivity § Selection of frequency bands to be monitored § Determination of alarm sensitivity (threshold for alarm according to reference value for

radiation). 3.1.3 Detector alarms

Fig.: PriSec ControlCenter displaying MobileWall alarms

Alarms are indicated acoustically and visually. The strength of the signal received allows ideally conclusions regarding the position of the illegal mobile device. Each alarm automatically generates a ticket. 3.1.4 System alarms All PrisonSecurity systems MobileWall are self-monitoring. All connected MobileWall devices are continuously checked for proper functioning. Detected errors are immediately reported and logged in the ControlCenter. Moreover, devices that are installed at locations where they could be target of vandalism are continuously checked for for tampering. The following alarms can occur:

§ Connection loss to MobileWall unit § Connection loss to MobileWall LineServer § Short circuit/Overload in a device bus connection § Opening sensor MobileWall plastic housing (optional) § 3D motion sensor (punches, opening attempts, illegal opening of the cabinet) § MobileWall LineServer leaving the permitted temperature range § MobileWall device leaving the permitted temperature range


3.1.5 Standard operating mode In AUTO mode, MobileWall Detectors continuously listen for transmission power of mobile phones. Simultaneously, a pulsing alarm icon marking the position of the reporting MobileWall device in the building plan as well as an alarm notification are displayed in the PriSec ControlCenter software. Furthermore, the event is logged in the ControlCenter’s monitoring log file. Prison staff is hence enabled to find the illegal mobile phone in the radius of one or more reporting MobileWall devices and to confiscate it. 3.2 MobileWall LineServer (PS-MW-LS) Fig.: MobileWall LineServer

The MobileWall LineServer is the central control unit for the MobileWall devices. MobileWall LineServer’s principal task is to provide the most efficient and easiest way of connecting the MobileWall devices. Therefore, MobileWall LineServer has the following functions:

1. Power supply of the connected MobileWall devices. The cabling requires one cable only. This cable ensures data connection and power supply (48V DC).

2. Data connection to the installed devices. The MobileWall LineServer provides a robust and extensively tested Pyxos bus for the connection to the devices. The bus topology offers decisive advantages e.g. in comparison to an Ethernet wiring (cable length, bus power, up to 12 devices per cable)

3. The integrated Ethernet switch allows for connecting several MobileWall LineServers to others with no need of a star topology,too.

4. Optionally, an external signal can be connected to the MobileWall LineServer that in the event of detection creates a visual light and acoustic alarm signal.

Further Characteristics:

§ Mounting option on the wall or in 19 "rack cabinet, 1U § Standard IEC connection (230 V / 50 Hz) § BUS connection for serial connection of mobile detectors: 2 terminals, 150W power supply § Connecting up to 12 detectors to one central unit § 4 RJ-45 connectors 10 / 100T § Serial connection of LineServers (daisy chaining) § Operating temperature: range from 0°C to 35°C § Configuration and settings via graphical web interface

3.3.3 Connection to the MobileWall LineServer Each MobileWall device may only be connected to one MobileWall LineServer. No MobileWall device may directly be connected to another power supply and/or another Ethernet. Power supply and data connection are always provided by a MobileWall LineServer. The cabling to the MobileWall devices is typically made of Cat 5 - Cat 7 cabling (according to the cabling specifications and the type of the MobileWall device to be installed on-site). The MobileWall device offers LSA sockets and RJ45 sockets enabling its fast and reliable connection to the MobileWall LineServer. 3.3.4 Frequency bands The following features and specifications describe the basic configuration of a MobileWall device:

§ Covered frequency bands in accordance with RATEL radio frequency bands: § E-GSM within the range 880-890 / 925-935 MHz § GSM within the range 890-915 / 935-960 MHz § DCS-1800 / DCS (2G / 3G / LTE / 4G) within the range 1710-1785 / 1805-1880 MHz § IMT (3G / LTE / 4G) within the range 1.920-1.980 MHz § LTE 2500/2600 within the range 2500 - 2570/2620 - 2690 MHz

§ excluding and adding frequency bands or parts of frequency bands can be user defined / customized

§ Sensitivity adjustment: 0 to -30 dB § Range: minimum 10m in the open, with concrete walls at a minimum of 5m § Antenna: Radial multiband antenna, antenna gain 0 to +3 dBi

4 MobileWall Deployment & Installation Every installation of MobileWall systems must be planned based on a site survey and its specific outcome for mounting locations of the devices. Please note the below general information about a standard implementation of MobileWall systems. 4.1 MobileWall Network Backbone With one or more Ethernet LAN switch(es) the MobileWall-Backbone is built. These components will be connected to the backbone switch(es):

§ PriSec ControlCenter Appliance § MobileWall LineServers (MW-LS) § Admin and monitoring PCs

The MW-LSs can be directly connected to the backbone switche(s) or can be connected to each other via the MW-LS integrated switch. With this method, the first MW-LS must be connected to a backbone switch while the second one can be connected to the first MW-LS and the third one to the second MW-LS. The maximum length of Ethernet cabling between two devices (Backbone switch to MW-LS and -MW-LS to MW-LS) is 100 meters. The below figure illustrates a sample backbone with blue lines for an installation with 3 MW-LSs.


Fig.: Sample backbone for an installation with 3 MW-LSs 4.2 MobileWall Detector Pyxos-Bus Topology The MW-LS offers a standard Pyxos device bus that MobileWall devices can be connected to. A MW-LS can be located at any position within this Pyxos bus. The line length of the bus must not exceed a maximum 100 meters at each side of the MW-LS. MobileWall Detectors are line-powered by MW-LS, there is no need for external power supply and electrical cabling to the MW. With line powered MobileWalls the maximum distance between a MW-LS and the last MobileWall device is 100 meters, accordingly the maximum bus length is 200 meters if MW-LS is placed in the middle of the bus (see the below figure). Regardless of MobileWall positions at one side or both sides of a MW-LS, maximum 12 MobileWall devices can be connected to one MW-LS.
